A traceless perfluorooctylsulfonyl tag for deoxygenation of phenols under microwave irradiation
摘要:
The perfluorooctylsulfonyl group is introduced as a traceless tag for solution-phase palladium-catalyzed deoxygenation reactions. The synthetic efficiency is improved by microwave irradiation for reaction and fluorous solid-phase extraction for separation. Further application of this traceless tag for multistep synthesis of substituted hydantoin and pyrimidine is also described. (C) 2004 Elsevier Ltd. All rights reserved.
